Reversing pest resistance to GM cotton

Insect pests that are rapidly adapting to genetically engineered crops threaten agriculture worldwide. A new study published in the Proceedings of the National Academy of Sciences reveals the success of a surprising strategy for countering this problem: Hybridizing genetically engineered cotton with conventional cotton reduced resistance in the pink bollworm, …

Barley genome sequenced

A group of 77 scientists worldwide have sequenced the complete genome of barley, a key ingredient in beer and single malt Scotch. The research, 10 years in the making, was recently published in the journal Nature. Barley is grown throughout the world, with Russia, Germany, France, Canada, and Spain being …

Tea tree genome contains clues about how one leaf produces so many flavors

The most popular varieties of tea—including black tea, green tea, Oolong tea, white tea, and chai—all come from the leaves of the evergreen shrub Camellia sinensis, otherwise known as the tea tree. Despite tea’s immense cultural and economic significance, relatively little is known about the shrub behind the tea leaves. …

Rice expressing mutant forms of GA 2-oxidase shows increased yield and tolerance to stress conditions

Optimizing plant architecture to increase yield, stress tolerance, and water use efficiency (WUE) is a major challenge for modern agricultural biotechnology. Gibberellins are growth hormones known to be directly related to plant height and tillering, which in turn are directly related to grain yield in cereals. GA 2-oxidase is a …

New sugarcane as a feedstock for biodiesel and ethanol

Biodiesel production in the U.S. from vegetable oils has increased substantially during the past decade. However, its further increase is limited by the low amounts of oil produced per hectare from temperate oilseed crops. Recently novel transgenic sugarcane has been developed to accumulate both sugars and lipids in stems, making …

Bulgarian tomato with high content of beta-carotene extremely suitable for organic farming

Under partnership between Agrobioinstitute, Sofia and the bio-farm Amitica Ltd, Kresna, the Bulgarian tomato cultivar Pako Orange was grown successfully under organic conditions. The first bio-seeds were produced. Production of bio-juices and bio-purees from tomato Paco Orange are planned. Tomato cultivar Pako-Orange was developed by methods of classical plant breeding-interspecies …

Aflatoxine-fee maize by using biotechnological approach

Researchers at the University of Arizona have found a promising way to prevent the loss of millions of tons of crops to a fungus each year, offering the potential to dramatically improve food security, especially in developing countries. The team’s approach uses transgenic corn plants that produce small RNA molecules …
